Line a baking sheet with parchment. Set a shallow bowl of confectioners' sugar nearby.
Warm cream, butter, lemon zest, and salt in a small saucepan until steaming, not boiling.
Remove from heat. Stir in lemon juice and lemon extract until combined.
Place chopped white chocolate in a heat-safe bowl. Pour hot cream mixture over it and let sit 2 minutes.
Stir slowly from the center until smooth and glossy. Microwave 5–10 seconds if a few bits remain.
Cover and chill until thick enough to scoop, about 60–90 minutes.
Scoop 1-tablespoon portions and roll quickly into balls. Place on the lined sheet.
Roll truffles in confectioners' sugar. For a shell, melt the optional white chocolate and dip, letting excess drip.
Chill 15 minutes to set. Keep refrigerated until serving.
Notes
Try rolling in toasted coconut, finely crushed vanilla wafers, or sparkling sugar. For extra zing, add a tiny pinch of citric acid to the coating. Store truffles covered in the fridge for up to 1 week or freeze up to 1 month; let soften a few minutes before serving.This recipe is an original creation inspired by classic Lemon White Chocolate Truffles Recipe flavors.
